To all whom it may co'rwern: Be it known'that'I, LEANDER citizen of the United States, of Lexington,

in the county of Middlesex .and State of Massachusetts, have invented a newand useful Improvement in Transmission Apparatus, of --which ,the following, taken in connection with the accompanying drawings, is a specification.

My invention relates to anapparatus for transm1tting power from a motor to the mechanlsm to be driven, and is so devised that as much or as. little of the power of the motor may be transmitted as may bo'desired, and that the direction of motion of the driven mechanism may be direct or reversed,

the object being .to avoid friction and noise and to produce a simple. easily-operated transmitter. This object I attain by the mechanism illustrated in the accompanying drawings in which Figure 1 is a plan view showing the ap-' paratus complete. Fig. 2 is a horizontal section Sh0W]J1g the interior construction, but omitting the indirect port-ways, showing the direct port-ways only; Fig. 3 is a horizontal section showingthe interior construction omitting the, direct port-ways and showing the neutral portways also omitting the other port-ways. Fig. 4 is a plan showing the system of ports and port-ways and the rotatable port-way carrier. Fig; 5.is a section through the port-way carrier taken on hne 55 of Fig. 4. Fig. 6 is a section through the port-way carrier'taken on line 66 of Fig. 4. Fig. 7 is a section ,ofthe port-Way carrier taken on line 7-7 of Fig. 4.

In the drawings the inclosing case is shown as made in three parts as follows: The part A, Fi 1, contains the transmitting motor that 'ves the working shaft D, that is, the shaft that communicates motionito the working agent directly or indirectly, for instance, in case this device is used in connectidn with a ropeller for a boat, the shaft D is connecte directly to the propeller .or

indirectly by any of the usual methods, and -m case the apparatus is used in connection with an automobile, then the shaft Dwill glige motion directly or indirectly to, the 'ving axle, other cases suggest'themselves. Thepart of the cas which are indicatedby E and F, aswill be fully explained hereinafter. I

also con- -tains the rotatingbuttre'ss t e. shafts of ing drumthat in turn contains the ports and port-ways. The parts B? and B act as coupling pieces, and incertain uses may serve to connect thepart-C directl to the part A,'in which event the part is not usedat all. a The part 0 of the case contains the li uid drivingl-device and is connected by the s aft C to t e prime motor, which may be ofany class.

The agent of transmission being liquid in this apparatus, 1 W111 describe the form of pump used for the purpose of causing a circus h the difierent he case 0 has within it a centrally located shaft C which receives motion from the rims motor and has keyed to it a hub C ig. 2, from which two concaved pistons C and C extend, as shown in the drawing. These curved pistons are not of the propeller type, but are simply curved as they extend radially from the hub. I] The rapid rotation of these pistons in the direction of the arrow will draw in the liquid through the pi e G and force it he circulation of the liquid is as follows: pump chamber 0, it passes through thepipes Hand H? to the port-ways in case B, thence through the pipes H and H to the transmitting motor driving; the transmitter, motor the hqurd passes out through the pi es Gr and G to the port-ways in the case thence throu h pipes G and G back to the pump 1n t e case GI The transmitter motor may 0 as follows; referring to Fig. 2: A c rcular chamber A is formed in the part A'of the case, in the center of which a piston-carrying drum D. is mounted upon the shaft D,

which, as has been explained, communicates nearly fluid-tight as possible,-in the circular chamber A and adapted to be'driven by the liquid that enters :throu h sage'I-P and passes out t on ht Gr". The buttresses-{E F or the motor "pistons.D*.D are circular andare mounted upon shafts E and F. I The diameters of the circular buttresses are each one-half of the diameter of the piston carrying D The pat B of the case contains the rotat- After leaving the 'in the case A.

The rotating buttresses E and F are each ma'dowith a recess E and F to admit of the passage of the ends of the iston D and D.

he parts are all; so. turne that the piston end will work correctly in the recesses E and F. It will be observed that the piston leave a assage for the li uid, so that no ocket or pack of the 'quidcan take p ace between the end of the advancing piston (D for' instance) and the rotating but' tress. A

A very essential and distinctive feature of my invention, is :the device that I have- "made fordirecting'and controlling the flow of the liquid that is used for transmittin the power. .This device is inore articu arly 'shown'in Fi 'I. 4, 5, 6 and 7, an consists of a rotatable having a shaft B-by which it may be turnedso' as to cause the port-ways to coincide .transmissionpipemG H and G H, The I drum B has alsov a short shaft or journal B upon which it turns. For convenience, .in referring to this drum B it Beitermed, the ort-way carrier, I 3 I -.T e ort-v'va s mayj be formed'bycores, in whic case t e carrier B would-beef cast metal: but the way that is illustratedjn the drawing is to formthe port-ways of metal on the ort-ways are straig the shown at K and 2 and 7, and thel 'ump piston- G rotates in the direction oft e arrow"Z-,- Fig, 2,: then the transmittingliquid is forced in the direction of the' arrows X, X,-. and the transmitter motor is .;to"ro-* it is desired to Site without stopping t e pump,- the port-way "08111611 B is turned so that the ort waye: III and L L see F'i pump throu h the pipesH I ort-way'L%l, -6, direct to the :pipcs G anii'b'ack tIo-the-puin notvfijowi'ng to; .t.;,-the transinitter.- motor at;Ia 1.

' om the above it is obvious that by turning the port-way carrier the transmitter motor may be made to turn in either direction, and also that it may be gradually started or stopped.

1n starting the pump the rotating pistons will simply cause the contained liquid to move round and round in the pump case, but as the speed increases the centrifugal action sends the liquid-int'o the pipe H, and thence through the pipes and port-ways back to the dnflowmg side, of the pump, acting on the transmitting motorin its passage. Although I have described a rotary driving pump and a transmitter motor, I do not wish to confine myself to any particular kind of pump or motor, as my transmission valve or '90 port-way carrier is the feature that I wish tosecure as my invention when used in this con: nection. It will be observed that m' port-way carrier not only acts as a multip e port-we. can rier, but also as a rotary valve,fand tat I have in a single device, having butone actuatin'g'lever, a multiple port-we carrier and a multiple valve operator; and t at this aim 1e devicefurnishes port-ways and valves t at provide for allcurrents; 14,. 6., the out and in vcurrent for the direct action; the out and in currents; for the reverse action, and also the neutralcurrent f which is without any .ob- 'structing angles 1 or-hhambers for disturbing eddycurrents. Q

Another advantageof my port way car -rier and valve deviceis 'that turning the carrierit is impossible to '0 en the ports for 'the reverse action until-t 'e neutral .ports" have been openedand the direct action orts closed; and thereverse of this is true; erefore therev ean be no interference of cuLents or strain on any part'ofthe apparatus.
